Fix HW checksum offloading.
- Enable ones specified in if_capenable and remove AXEN_TOE macro.
- Check correct bit and set appropriate csum_flags.
- Pass packets of wrong checksum to upper layer instead of dropping them.
- Fix value of AXEN_RXHDR_L3_TYPE_MASK.

Tested on ASIX Elec. Corp. (0xb95) AX88179 (0x1790).

Fix previous:
- axen_coe() should be called from axen_init(), not axen_ax88179_init().
- Simplify logic in axen_coe(); AXEN_[RT]XCOE_OFF = 0.

Enable hash-table-based multicast filter:
- Drop AXEN_RXCTL_ACPT_PHY_MCAST bit (neither Linux nor FreeBSD sets it).
- 0x0010 bit is not AXEN_RXCTL_ACPT_BCAST ("accept broadcast") but
   AXEN_RXCTL_ACPT_MCAST ("accept multicast (hash-table-based)").

Remove useless memset.

Fix padding for a full length USB packet in TX:
- Update boundary length for SS mode, taken from OpenBSD.
- Make sure everything passed to the adapter is little endian.
- Specify padding bits in a similar manner to Linux.

XXX I wonder whether this is really necessary...

Support TSOv4 (They call it LSOv1).
The adapter does not support TSOv6 (aka LSOv2).

Fix previous.

Oops, fix previous again. Really support TSOv4.

Use unsigned variables for buffer length to avoid compiler warnings.
